Hi, by my reading of 'man s_client', you have turned **off** ssl v3
-ssl2, -ssl3, -tls1, -no_ssl2, -no_ssl3, -no_tls1, -no_tls1_1,
these options disable the use of certain SSL or TLS
default the initial handshake uses a method which should be
compatible with all servers and permit them to use SSL v3,
or TLS as appropriate.
